Abstract
Embodiments herein relate to a method in a first network node (16) for enabling device to device, D2D, communication between a first device (10) and a second device (13). The first device (10) is served by a first public land mobile network comprising the first network node (16) and the second device (13) is served by a second public land mobile network. The first network node (16) receives, from the second device (13), via the second public land mobile network, or from the first device (10), a request for permission for the second device (13) of roaming to the first public land mobile network enabling the D2D communication. The request requests access to a resource controlled by the first network node (16) of the first public land mobile network. The first network node (16) decides whether to grant the request based on a position related information of the second device (13) and/or the first device (10).
